Terrible Product
I purchased this for my Kohler cast iron tub, which is textured on the bottom. It ended up staining my tub. Terrible product.

Cast Iron Cleaner
I love this cleaner for my sinks. They are still beautiful after 6 years. I clean with dish soap regularly and the cast iron cleaner once a week and it keeps the sinks like brand new. Thanks Kohler.

Excellent cleaner!
Great job removing any stains or scratches—best cleaner I've found for my Kohler sink.

It's got its uses!
While not the best "get down and clean" product, it does put a gorgeous lustre on antique sinks (of which we have a few)! Not what I would use in the kitchen though--not tough enough on stains.

Outstanding product
I had a small scratch in my tub, so I ordered this product to try to fix it. I put off using it because I didn’t really expect it to work. When I finally tried it, the scratch immediately disappeared. I was extremely pleased with the results.

Did not work to restore the shine to the enamel on sink.
I was trying to restore the shininess to my Koehler enameled bathroom. I had tried recommendations I found on line. I found this when I visited the Koehler site. I bought it & tried it . It still did not restore the shininess to the enamel.
